Sync on green could be done with the ATI Mach 64 as well. I picked up a 20" SGI monitor (if memory serves, it was made by Hitachi) on the "free" table around 1999 on my university campus. I got it working, but the one I had was pretty limited - it did a specific resolution at 60 Hz (I may have the details wrong - it was a long time ago). I never ended up using it, as I had a newer 17" DEC Trinitron from an old Alpha 3000/300LX that I also got super cheap, and it was a much better screen.
